Examples

oneCmt <- function() {
  ini({
    tka <- 0.45
    tcl <- log(2.7)
    tv <- 3.45
    add.sd <- 0.7
  })
  model({
    ka <- exp(tka)
    cl <- exp(tcl)
    v <- exp(tv)
    cp <- linCmt()
    cp ~ add(add.sd)
  })
}

oneCmtOde <- linToOde(oneCmt)



pkpd <- function() {
  ini({
    ka <- 1
    cl <- 2
    v <- 20
    kin <- 1
    kout <- 1
    ec50 <- 2
  })
  model({
    cp <- linCmt(ka, cl, v)
    eff(0) <- 1
    d/dt(eff) <- kin - kout * (1 - cp/(ec50 + cp)) * eff
  })
}

pkpdOde <- linToOde(pkpd)
